Betting on Girona is very risky, especially now that Barcelona is in a comfortable condition to win the match. I don't think I will risk betting on Girona in this game.
Barcelona have a good record in the La Liga, they have kept 20 clean sheets this season and even with three changes that the Barcelona coach have made to the team, they will still win because the players who are starting are still very capable. Girona have never won Barcelona, the players may want to change that history in this game and will put in their best, but regardless I do not think they will be able to win Barcelona. If you bet on Barcelona to loose, you are very likely to loose tonight.
barcelona is getting tougher when at home, the 4-0 defeat to madrid in the recent el clasico will not affect barcelona's performance against a team like girona
besides that, since the start of the season, barcelona has only lost 2 times, while girona has lost 11 times. I believe the final score in this match is 3-0 for Barcelona to win
